dc.description.abstract | The experiment was conducted at the research field, Department of Agronomy, Hajee
Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during
January to April, 2017. The experiment was laid out in Randomized Complete Block
Design (RCBD) with three replications. The experiment was consisted of two factors viz.
factor A: B1 = 0 kg B ha-1, B2 = 5 kg B ha-1, B3 = 10 kg B ha-1 and B4 = 15 kg B ha-1
, and
Factor B: Zn1 = 0 kg Zn ha-1, Zn2 = 10 kg Zn ha-1
, Zn3 = 15 kg Zn ha-1, and Zn4 = 20 kg
Zn ha-1. Data were recorded on different growth and yield contributing parameters. Most
of the parameters showed significant difference among the treatment. Results indicated
that the highest plant height (92.91 cm), panicle length (28.30 cm), number of filled
grain panicle-1 (186.1), number of total grain panicle-1 (203.1), grain yield (4.93 t ha-1),
and harvest index (35.69%) was recorded from B3Zn3. Whereas the highest values of
number of non-effective tiller hill-1 (8.25) and number of un-filled grain panicle-1 (31.00)
were recorded from the treatment combination of 0 kg B ha-1 and 0 kg Zn ha-1 i.e. B1Zn1
treatment. At 50, 60 and 70 DAT, the highest grain growth rate (0.029, 0.032 and 0.0390
g) was found from the treatment combination of B3Zn3 (10 kg B ha-1 and 15 kg Zn ha-1),
whereas the lowest grain growth rate (0.011, 0.019 and 0.0130g) was observed from the
treatment combination of B1Zn1 (0 kg B ha-1 and 0 kg Zn ha-1) at same DAT. The
treatment combination (B3Zn3) performed better for increasing the grain growth and
yield of Tia rice. | en_US |
